After two hours of cultivating and using up almost all the crystal cores they had on them, Chu Miao and Ye Xuan left their cultivation state at the same time.
They were quite synchronized.
"Have you recovered?" Ye Xuan asked Chu Miao when he realized that she had also stopped cultivating.
"Yes, let's go get rid of those zombies then collect our crystal cores." Chu Miao replied and walked to him, held his hand, and teleported outside the building.
They landed at a spot that was not very crowded with zombies as most of the zombies had left and others were still roaming around, but without a clear target, they were no longer clustered together.
When they landed, the zombies near them rushed towards them and started attacking them again.
They repeated the same fighting style of standing back-to-back and resumed their onslaught.
They killed zombies until 3.00am in the morning before clearing the last batch.
